What is the difference between corrosive and caustic?
« on: January 28, 2015, 01:23:46 PM »
I've read on wikipedia and other websites several opinions about this topic.
In my opinion it's a convention to call caustic bases and corrosive acids, because the two words have the same meaning.

Could you help me?

Look up the reaction of bases and acids with many substrates.  Yes, in fairly dilute solutions, they react the same to our skin.  But what about their reactions with wood, paper, cloth and especially, metal?

Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

I think that when an acid reacts with paper, cloth and metal it's stronger than a base. A base is a bit slow when it reacts with a metal but, as time passes, it continues to corrode the metal.  I can see that acids and bases produce two different kinds of corrosion. Isn't it?
